Zacctly, high volume/high pressure
oil pumps and fuel pumps and under-drive pulley sets and other "race" parts are designed for dedicated race engines with certain rpm ranges and bearing clearances, they are not designed nor suited for street cars...In some instances, they do more harm than good!!!!!!!!!!!!!
NASCAR enignes are rebuilt after every race,road race engines are rebuilt after as little as 30 hours of run time, I stretch mine to 50 hours. There are many things on my road race motor I would never put on my street motor..........
